The Magnificent Frigatebird (Fregata magnificens) was sometimes known as the Man O'War, reflecting its rakish lines, speed, and aerial piracy of other birds. It is widespread in the tropical Atlantic, breeding colonially in trees in Florida, the Caribbean and Cape Verde Islands. It also breeds along the Pacific coast of the Americas from Mexico to Ecuador including the Galapagos Islands. The Magnificent Frigatebird is 100 cm (39 in) long with a 215 cm (85 in) wingspan. Males are all black with a scarlet throat pouch which is inflated like a balloon in the breeding season. Although the feathers are black, the scapular feathers produce a purple iridescence when they reflect sunlight. Females are black, but have a white breast and lower neck sides, a brown band on the wings and a blue eye ring. Immature birds have a white head and underparts.
